Inquire nowIn order to be compacted, the mixture must have controlled workability. Typically, for dense-graded mixes, a lift thickness of 3 to 4 times the nominal maximum size (NMS) of the aggregate is needed. For example, a mix containing ½-inch NMS stone should be placed at a compacted depth of at least 1-½ to 2 inches.

Inquire nowThe Marshall method is a holistic approach to asphalt pavement mix design. Through a series of steps, it is able to establish the ideal asphalt content for a mix that will provide maximum strength and stability for its load. Through Marshall testing, engineers are able to: Select mineral aggregate and binder materials.
