Module 3 – 13 Minutes
Pothole Repair in Asphalt Concrete Pavement
Potholes must be repaired quickly because they are a safety hazard. They damage vehicles and quickly lead to further, more serious road damage. Done correctly, the repair will last a long time. Done poorly, it can soon become a growing expense. Through a detailed 9-step procedure using proper materials, tools and equipment, the tape shows and explains how to do each step correctly and efficiently, with the result of a long-lasting repair. Special emphasis is placed on the proper shaping of the repair and the compaction of the mix.
Module 4 – 14 Minutes
Pothole Repair in Surface Treatment Pavement
The correct procedures for use of granular material for filling the pothole are demonstrated and explained. They will provide a long-lasting repair. Proper equipment and materials used for repair are discussed. An 8-step procedure is demonstrated in detail.

Actual repairs of linear cracks and area cracks are demonstrated.
Module 6 – 14 Minutes
Repair of Depressions, Rutting and Corrugations
The basic repair method for depressions, rutting and corrugations is to fill in the low areas with a leveling course of asphalt concrete and then to overlay the entire area with a wearing course. The proper procedures to perform this repair method with a motorgrader are described through eight work steps. Special considerations for placing and compacting each layer in a deep depression are illustrated. The tape also shows how to place and compact a thin overlay over the leveling course.
Module 7 – 16 Minutes
Base and Sub-base Repair
Details on correct procedures for the repair of base and sub-base are demonstrated in this videotape. Nine work steps include placing the traffic control devices, marking the limits of repair and cutting the pavement, removing all unsuitable material, installing required sub-drainage, restoring the sub-grade, replacing the sub-base and base, replacing the pavement surface, cleaning the work site and removing the traffic control devices. Quick on-site tests of the moisture content of the sub-grade and base materials are also shown.
Module 8 – 15 Minutes
Single and Multiple Surface Treatments
This module gives the What, the Why, and the How in construction of successful surface treatments on unpaved and paved roads. It covers good construction practices in eight detailed work steps. The preparation of the surface to be treated, testing of the asphalt distributor, and checking the weather are discussed. Materials required for surface treatments are presented. Proper procedures for applying the asphalt, spreading the aggregate and compacting the aggregate are demonstrated. Construction of smooth transverse and longitudinal joints is also described.
Module 9 – 24 Minutes
The module describes an increasingly useful and cost-effective method of maintaining paved surfaces. It covers the resources needed to perform a slurry seal job including materials, equipment and manpower. It also shows in detail the slurry seal operation in 7 steps: storage and loading of materials, traffic control, surface preparation, slurry application, curing, rolling and clean-up. Applying these procedures, the pavement will be protected with a uniform skid resistant and waterproof surface.
Module 10 – 12 Minutes
Patching Unpaved Roads
This is a manual method of maintenance for repairing surface defects such as potholes, ruts, gullies and soft spots on unpaved roads. The Module describes an eight-step maintenance procedure to provide a long-lasting repair. Proper maintenance practices for preparing the hole, filling it with granular material and compacting the material are shown in detail. A quick test for moisture content of the material at the site is also described.
Module 11 – 21 Minutes
Smoothing and Reshaping of Earth and Gravel Roads
Regularly scheduled smoothing and reshaping will keep earth and gravel roads in good condition and reduce the need for major high cost repairs. This videotape has two parts: (1) Smoothing, and (2) Reshaping. Each part has an equipment requirement, and overview of work steps, the work steps in detail, and a work step summary. Considerations for planning and preparing for the work are treated. Procedures for checking the road cross slope at straight and curved road sections are also presented.
