Rosco CSV - Totals;Auto Resume Screen; Preparing to Chip Spread

Totals/Auto Resume Screen
The Totals/Auto Resume screen performs two functions.
Auto Resume calibrates the automatic resume function
when returning to forward propel while operating in the
Auto mode. (Figure 4-21) Adjustments are made in
increments of inches. Button 1 increases the setting
while Button 2 decreases the setting.

2 - Auto Resume Decrease
The screen displays the total miles and total tons.
The operator can reset the total miles and total tons
by pressing the last button on the right side of the
controller (reset is illuminated on the screen). Press
the right arrow button to increase; press the left arrow
button to decrease.
PREPARING TO CHIP SPREAD
Chip sealing is the application of bituminous binder
immediately followed by spreading aggregate. The
aggregate is then compacted (rolled) to embed into the
binder. Single or multiple layers can be applied using
various aggregate and binder types depending upon
the pavement distress or trafc situations. Binder types
vary, but are usually polymer-modied emulsions (PME);
performance-based asphalt (PBA) cements; asphalt
rubber (AR), which require hot chips pre-coated with
asphalt; and rejuvenating emulsion.
Figure 4-22. Chip Spreading
The Rosco CSV Variable Width Chip Spreader is
capable of spreading a wide variety of aggregate onto
the surface treatment of asphalt pavements. The chip
spread paving technique seals the asphalt surface from
weathering caused by water and air permeation, and
aids in preventing trafc wear to the pavement. It’s a
very economical means of resurfacing roads because it
has a longer life and offers good water drainage.
The CSV chip spreader produces a higher duration
chip seal due to the aggregate separation effect of the
spread roll. The rotation throws larger aggregate ahead
so they land in the asphalt before the smaller particles.
The smaller particles then “chock” the larger particles
into place, thus bonding better with less chance of
loosening by trafc and causing damage to vehicles.
The main advantages to chip seals include:
• Improved Skid Resistance and Durability: Chip
seals provide excellent skid resistance, wear well and
have long service lives.
• Cost-Effectiveness: Chips seals are typically more
cost-effective when properly placed on the right type
of pavement.
• Ease of Construction: Chip seals typically require
less construction time and cause less disruption to
trafc.
