How it
Works
California Pavement Maintenance Co.'s RoadSaver ll®
From a platform at the back of the truck-mounted
RoadSaver ll® from California Pavement Maintenance Co. Inc.,
Sacramento, Calif., an operator can monitor aspects of material flow as he or
she places an emulsified mix on a road surface. With the press of a button at
the operator's control center, the operator can set the computer-controlled,
automatic sequencing material introduction system in motion. The manufacturer
states that this introduction system allows timing adjustments for delivering
aggregate, emulsion, water and additives into the pugmill where they are mixed
and distributed to the road surface.
To pour an emulsified mix from the RoadSaver ll, the crew first delivers
aggregate to the aggregate bin, which is designed to hold 12 cubic yards (9.2 cu
m) of material. Aggregate travels on a hydraulically driven RSII SuperBelt
conveyor to the reversible, twin-shaft, twin-drive pugmill A centrifugal 130
gallons (492 L) per minute pump delivers water from the 750-gallon (2,839-L)
water tank and a Blackmer positive displacement vane pump delivers the emulsion
from the 600-gallon (2,270-L) tank, both located at the front of the machine, to
the pugmill to be mixed with the aggregate.
For mixes that require other additives, a 90-gallon
(340-L) liquid additive tank sits toward the back and on the right-hand side of
the machine, delivering material via a hydraulically driven pump, which is
adjustable at the operator's station. A 16-cubic foot (0.45-cu-m) fines feeder
sits above the aggregate bin at the back of the machine, delivering material via
a digital ratio meter, and is also adjustable at the operator's station.
Electronic sensors and digital displays monitor the
rate at which materials enter the pugmill for mixing, and the speed at which
they are mixed. If the sensors detect variation, they are designed to either
shut down operation or alert the operator.
Once materials are flowing to the pugmill at a
metered and monitored rate, the multi-paddle pugmill mixes the materials and
augers them out through the hydraulic gate and diverters to a spreader box, or
other end attachment, at material output rates ranging from 2 tons to 4 tons
mixed (1.8 to 3.6 Mg) per minute, according to the manufacturer. With the
automatic sequencing material introduction system, the operator can set or
control which material precoats the aggregate, and for how long, before the next
material enters the pugmill.

Slurry & Penguins at
the "Edge of the Earth"
When a customer
buys a RoadSaver slurry machine, if they need assistance CPM staff goes to their
place of business and gives them training and instruction on the use and
maintenance of slurry equipment.
 Last year, when a
customer in South America requested such guidance for their newly acquired
RoadSaver, Gordon Rayner was more than happy to send training staff to Chile to
give assistance. He expected the project to be in or near Santiago, "a beautiful
city with ideal slurry weather." However, their project turned out to be at the
"end of the earth."
The company, Navarrette Y Diaz Cumsille is located in
Santiago, Chile, but their upcoming project was to be at Punta Arenas, at the
bottom of South America, almost at the South Pole. There were no roads from
Santiago to Punta Arenas and no way to get there by land from Chile because of
glaciers. Gordon was also informed that one of the main attractions at Punta
Arenas is Penguins. He was further advised that there were only three weeks of
summer there, with temperatures sometimes reaching 50 degrees, with a constant
wind of 30 to 40 knots. The project was beginning to sound like a real
challenge.
 Founded in 1848,
Punta Arenas was originally a military garrison and prison. During the
California Gold Rush it proved convenient for shipping. Ships from Boston and
San Francisco would meet at this remote port to trade. When the Gold Rush ended,
the Punta Arenas economy became more dependent on animal products, and by the
turn of the century over 2 million animals grazed the territory's natural
grasslands.
As the largest port for thousands of miles, Punta Arenas
attracts ships from a large South Atlantic fishery as well as Antarctic research
and tourist vessels. But now, ships began to arrive with a new cargo - CSS-1h
Slurry Seal Emulsion. The emulsion came to Punta Arenas the same way the
RoadSaver II did, by way of ships through the Straits of Magellan.
The emulsion was delivered to large square holding tanks
moved in for storage at their stockpile. The project itself was 40 kilometers of
two-lane road, fairly flat and straight, outside Punta Arenas.
 The aggregate was
made nearby (about 40 km away) by Navarrette Y Diaz. Making aggregate in these
latitudes was a real challenge. The wind in that part of the world never stops
and the fines were very hard to control with the constant wind. To accomplish
the needed gradations, the aggregate was crushed in various sizes and then
blended in a machine that has an electronically metered loader bucket which
picks up measured amounts from each of three plies of aggregate. The materials
were then deposited into a drum, which blended the material in a manner similar
to a concrete mixer. The finished aggregate was then delivered to the stockpile
where it was hand screened and loaded into the RoadSaver II.
Water was trucked the 50 kilometers from the water
treatment plant. It presented some minor challenges as the pH varied from 5.0 to
7.2 during any given day.
The RoadSaver II was delivered by ship to Punta Arenas and
driven to the work location. With all the materials and the RoadSaver now on
hand, the crew performed a calibration under the guidance of Angel Arenas,
Quality Control Engineer for Navarrette Y Diaz. The RoadSaver was set to deliver
the proportions called for in the mix design and work began.
The machine operator, Amador Agurto, had previously worked
as an asphalt plant (hot mix) operator and had never seen slurry before. He
received initial training from CPM on the RoadSaver prior to the machine being
shipped from Santiago. With the natural feel and intuitiveness of the Road Saver
joystick controls, Amador was soon placing slurry at 4 tons a minute. This was
important as long shuttles (as much as 20 km each way) and short hours made
production time very limited.
They were fortunate to have a latex modified cationic
emulsion which offered the stability needed for ocean shipment and yet allowed
reasonable set times. During the time Francis and Alex were there, the weather
was really difficult as temperatures seldom got above 5 to 7 Celsius (40 to 45
degrees F.) for more than an hour or two. With a constant hard wind, storms
would blow in suddenly and then disappear just as quickly Francis and Alex made
their first purchase, new winter jackets for "summer" use.
Weather conditions restricted the daily hours of placing
slurry and with only one slurry machine on the job, combined with the long
shuttles, production was limited to about 130 tons per day.
The slurry was placed over a tack coat of CSS- 1 spread at
600 Grams/Sq. Meter (. 13 Gallons per Sq. Yard), at 8mm in thickness. Cement was
used as an accelerator at .8% and with the help of winds, even with the cold
temperatures, set times of under an hour were achieved.
Vehicle traffic was not a major problem, although
occasional large herds of sheep made sweeping the road "difficult," Other
livestock obstacles included emus and llamas (The penguins never became a
roadway problem, since they prefer the water and build burrows in grass).
 Teaching a new crew
the principles of slurry seal at the earth's edge added new challenges. As
Francis related, "The aggregate fines were constantly under attack by the never
ending wind so we had to cover the stockpile to prevent fines loss. Each new
load of recycled water had a new pH and we were constantly keeping an eye on
that. Set times were critical because it would seem nice one minute and a storm
would move in the next. This is the first time I ever had to wear a parka while
laying slurry."
CPM is fortunate to have Francis Cardoza, who speaks and
understands basic Spanish, and Alex Garcia, who is fluent in Spanish. With their
years of slurry/microsurfacing operation and supervisory experience, Francis and
Alex combined to transfer this knowledge to this new crew. Francis taught
machine operations and crew techniques. Alex worked with Jorge Leiva, the
engineer in charge of the overall project, and Angel Arenas, the quality control
engineer, on construction procedures, material specifications, slurry chemistry
and logistics. "Logistics," related Alex, "becomes a whole new subject when your
emulsion is being delivered by ship!"
Dependability in equipment became critical here too. With
glaciers, penguins, logistics, supply problems, winds, cold and stormy weather,
this crew faced a lot of obstacles. But one problem they didn't have was the
RoadSaver.
When the training was over and the crew was performing on
their own, Francis and Alex had only one item left on their list to accomplish.
A visit to the home of the Magellanic Penguin colony to have their picture taken
with the penguins. This was for proof after all, who would believe that they
taught slurry at the end of the earth?
