This presentation will cover keyhole coring, vacuum excavation and pavement restoration processes for utility work under urban streets and sidewalks. Whether new utility lines are being installed or existing services are being rehabilitated or maintained, subsurface utility work frequently involves cutting...

This webinar will present the research findings of the Mountain-Plains Consortium Research Project 480. This research was based on innovative geometric designs as a solution to the challenge of increased traffic volume with limited resources. This particular study focused on diverging diamond interchanges. The...

Procedures used for aggregate sampling. The course provides insights into the definition of aggregate, methods of processing and the various methods of sampling.

This short module introduces the learner to modules on the soil moisture-density relationship and soil drying methods.

This module covers the process of determining the total moisture content of a soil using a microwave or an oven. Each section explains when you would normally use the method, the equipment you need for that particular method, and how to conduct the procedure. It also shows how to calculate and record...

This module covers the process of determining the maximum dry density and optimum moisture content of soils using AASHTO T 180 Method A. It includes:Compaction, density and maximum dry density definitionsHow to verify effort on embankment and if the road is properly compactedMoisture density relationship...

This modules covers the process of determining the maximum dry density and optimum moisture content of soils using AASHTO T 180 Method A. It is a shorter version of the Proctor Test module; however, this module includes the following:Equipment needed to conduct the testWhat a mositure-density relationship...

This course covers mechanical splitting and quartering of aggregates, including information on sampling, particle and sieve sizes.

This module will give the learner a basic understanding of the Rubber-Balloon test. It includes: The process of determining in-place density of compacted soil How to determine if a roadway embankment is properly compactedThe purpose of the Rubber-Balloon test and the equipment needed to conduct the...
