Chip Seal Design Methods. Vishwanath Pothukutchi. Introduction. Early practitioners used empirical methods to design sealing a pavement. It was considered an art. The Design involves calculating : Quantity of aggregate Quantity of bituminous binder. Introduction.
Basic Principles :
Equations for Aggregate spread rate are as follows:
V is the % of voids in loose aggregate
H is the average least dimension
G is the bulk specific gravity
E is the traffic whip off factor.
B is the binder spread rate.
H is the Average least dimension
T is the Traffic Volume Factor
S is the Surface factor and
A is the absorption factor and R is the % of asphalt
