Hot mix asphalt paving materials can be manufactured by: (1) batch mix plants, (2) continuous mix (mix outside dryer drum) plants, (3) parallel flow drum mix plants, and (4) counterflow drum mix plants. This order of listing generally reflects the chronological
10.3.2.6 Stone mastic (matrix) asphalt SMA is a relatively thin (12.5–40 mm) gap-graded, densely compacted, HMA that is used as a surface course on both new construction and surface renewal. It is a mixture of asphalt cement, coarse aggregate, crushed

3.1 Introduction. The required analytical method of flexible pavement design is FPS 21. FPS 21 uses a systems approach centered upon deflection measurements from the falling weight deflectometer (FWD). These measurements are then used by the MODULUS computer program to estimate the material properties (modulus) of the pavement layers through a
ent names: hot mix asphalt, plant mix, bituminous mix, bituminous concrete, and many others. It is a combination of two primary ingredients - aggregates and asphalt cement. The aggr egates total 90 to 95 per cent of the total mixture by weight. They are mixed
3-4 SIMILAR OPERATIONS OF BATCH AND DRUM PLANTS Certain plant operations are common to both the batch plant and drum mix plants. These operations include: 1) Cold aggregate storage and feeding 2) Dust control and collection 3) Mix storage
The Asphalt Institute recommends a transverse slope of between 1.5 to 3.0% on all pavement surfaces, and an even steeper slope of 3 to 6% on shoulders. Maintaining a slope of at least 1.5% on parking lots will ensure proper surface drainage (no ponding or birdbaths) and minimize infiltration, hydroplaning and the detrimental effects of water.
