213R03 Guide for Structural LightweightAggregate ConcreteFor example, assume the inplace cost of a typical short span bridge may vary from 50 to 200 /ft 2 (540 to 2150 /m ). If the average thickness of the deck was 8 in. (200 mm) then one cubic yard (cubic meter) of concrete would yield approximately 40 ft2/yd3 (5 m2/m3).
Section 3: Selection of Aggregate SearchThe target value of precoating material typically varies from to percent ( to percent for lightweight aggregate), by weight, of residual binder on the aggregate. When the seal coat binder is to be an asphalt cement, precoating of the aggregate is recommended to maximize adhesion and reduce the adverse effect of dust.
