Permeability properties and the CBR. of the compacted soil mixing asphalt and Para-rubber

Abstract

Thailand and other countries In bar with hot air Laterite a material that is readily available . And used as surface materials and the foundation for construction of roads and airports. Widely Laterite several mechanical properties include Aggregate Impact Value and California Bearing Ratio (CBR) , which these values are very useful for the selection of gravel as construction materials . Provide even better performance concept study is to improve the soil with asphalt cement and rubber. Laterite updated with latex the two types were tested in compression unlimited scope Unconfined Compressive Strength (UCS) and test the strength bearing California Bearing Ratio (CBR) for the experiments used in the force . bearing strength and volume of permeable material . Test results for the bearing (CBR) materials with improved quality gravel , asphalt cement and rubber . Found that the bearing (CBR) has increased the quantity of asphalt cement and rubber . Compared to standard surface. ( Tl.-m. 201/2544 ), namely the bearing (CBR) is greater than 80 percent , based on the test bearing (CBR) with water as it is to consider the design of the road. Thus, the amount of asphalt cement and rubber to improve soil quality is the most appropriate . Amount of asphalt cement 3.0 percent and 6.2 percent water timber.
