ST9601-CS 970520 WRANGLER ROAD
CONSTRUCTION ESTIMATE
Design and estimate of costs to reconsmact Wrangler Road, from Belt Line Road to 3,168 LF west,
to carry 80,000-1b. wheel loads:
ROAD DESIGN AND LIMITS
The existing roadbed is 24 feet wide with 24 feet of pavement. To stay in the limits of the existing
drainage structures, we can only widen the road to 28 feet. The new design will be 28 feet wide with
2-foot support shoulders on both sides which will be marked with continuous white stripes, leaving
24 feet for two 12-foot traffic lanes. The existing road materials will be milled and salvaged for
processing at the TXI plant in Coppell. Subgrade will be undercut to accommodate 9.5 inches of
cement treated base (CTB) and 2.5 inches of hot mix asphattie concrete (HMAC).
Road Design Limits and Summary
1) From Belt Line Road to 3,168 LF west
2) 28-foot wide roadbed
3) 9.5 inches of CTB
4) 2.5 inches of HMAC
This gives a one foot design of select materials.
