  Prerequisite: CE 341, CE 343.

Textbook:             Hot Mix Asphalt Materials, Mixture Design and Construction, by Roberts, F., Kandhel, P and Brown E., 1996.

Reference:            None     

Coordinator:        Ibrahim M. Asi, Assistant Professor of C.E.

Goals:    This course has been designed to introduce students to the concepts of highway and airport construction and maintenance techniques.

Prerequisites by Topic:     

1.           Soil classification, testing.

2.           Asphalt concrete design.

3.           Material testing.

Topics:

1.           Introduction: construction materials, asphalt plants type; batch plants, travel plants, drying drum plants…,  cement plants operation process (2 classes)

2.           Construction: material selection, placement and compaction, compaction procedure, compactor types (steel drum, sheepfoot)  (3 classes)

3.           Superpave asphalt binder tests and specifications (3 classes)

4.           Hot-mix asphalt mixture design methodology, history, objectives, Marshall, Hveem & superpave mix design (4 classes)

5.           Inspection: work inspection, quality control methods, stage construction (3 classes)

6.           Pavement Performance: performance evaluation techniques, concepts of roughness, skid resistance (2 classes)

7.           Pavement Condition: evaluation of roughness and skid resistance; pavement evaluation methods and devices (2 classes)

8.           Pavement structural evaluation: destructive and non-destructive pavement testing techniques (Benkelman Beam, Dynaflect,  Falling-weight deflectometer, etc.) (3 classes)

9.           Pavement distress: types, causes, identification (3 classes)

10.         Pavement maintenance: distress maintenance techniques; crackfilling; patching local specifications (3 classes)

11.         Surface treatments: types, design, application techniques, and uses (3 classes)

12.         Pavement recycling: recycling techniques, uses, hot pavement recycling methods (3 classes)

13.         Hot-mix asphalt additives and modifiers (3 classes)

14.         Pavement overlays: techniques for pavement maintenance and rehabilitation (3 classes)

Computer Usage:  A number of computer softwares are used both in classes and homework assignments in Marshall mix design, introduction to SHRP performance grading,  pavement management condition surveys, and overlay designs. 

Laboratory Projects:   Since a lab is not assigned to the course, different laboratory projects covering HMA design, asphalt performance grading, asphalt modification and condition surveys are assigned to different groups of students.  At the end, presentations of all projects are made by the different groups.
