Conclusion
From rubber Cement Asphalt properties education equivalent of Natural rubber with Asphalt Cement (NRA) found that.
1. Compound characteristics of natural rubber with asphalt cement that is found to be higher than cement asphalt. It help percolation decrease.
2. Viscosity effects of natural rubber with asphalt cement will have a higher value than cement asphalt. It mixed asphalt is homogeneously.
3. Speed characteristics of hardening was found mixed asphalt that have speed characteristics of hardening more than cement asphalt.
4. The comparison showed that natural rubber with asphalt cement get more force than cement asphalt.
Considering the studies indicated that the Asphalt Cement with Natural rubber (NRA) will be better qualified Asphalt Cement have the appropriate qualifications to apply for work and have low-cost as well as Natural rubber (NRA) is a resource that exists in country Thai Natural rubber price problem (NRA) slump and market as well.
