Economic bituminous treated bases
Abstract
The use of low quality, lower cost, local aggregates in asphalt treated base courses in Texas was studied. Five marginal aggregates were investigated together with three sands and a sand gravel mixture. Results indicate that several of the marginal aggregates can be utilized as bituminous stabilized base courses provided that strict quality and construction control measures are employed. Additionally, these materials must be used under traffic and environmental conditions which are compatible with the stabilized mixture properties. An economic analysis method shows that mixture design and pavement design considerations cannot be separated.
