| Summary: | In a hot climate, asphalt pavement will age harden faster and require substantial
maintenance. Age hardening causes asphalt to be stiff and brittle. The pavement layer
then becomes too hard and lose its flexibility. As a result the pavement will crack and
break up. In this study natural latex is added to asphalt in order to retard age
hardening. The following tests were carried out on the latex-modified asphalt:
penetration, softening point, absolute viscosity and kinematic viscosity. Latexmodified
asphalt with latex content of 3% and 6% by weight of mix produce different
properties to justify their uses in different conditions. Six percent latex content was
found to be the optimum content in retarding ageing process of asphalt as well as
improving its stability. However the asphalt becomes less workable. Asphalt with
three percent latex content is found to be good in workability and at the same time
retain the ageing process as well as improving the stability of the asphalt |
