The Virginia Transportation Research Council (VTRC) has released five new research studies over the past two weeks, providing valuable insights to improve construction practices, materials performance, and transportation infrastructure across the Commonwealth.
The newly published studies include:
- Mechanistic-Based Evaluation of Performance Thresholds for Balanced Mix Design Asphalt Surface Mixtures – An in-depth analysis aimed at refining performance thresholds to ensure durable, cost-effective asphalt surface mixtures.
- Evaluation of Fiber-Modified Asphalt Mixtures Using BMD Tests – This study examines the performance of fiber-modified asphalt using Balanced Mix Design (BMD) testing methods, with the goal of enhancing pavement strength and longevity. Read the study here.
- Roundabout Construction Using Precast Concrete in Virginia – A review of the feasibility, benefits, and challenges of building roundabouts with precast concrete components to improve construction speed and quality.
- Use of Nuclear Gauge for Construction Quality Control of Unbound Base Course Containing Reclaimed Asphalt Pavement – This research evaluates nuclear gauge technology for ensuring consistent quality in base courses that incorporate reclaimed asphalt pavement.
- A Practical Oven-Aging Method for Evaluating Long-Term Cracking Performance of Asphalt Mixtures in Virginia – A study presenting a practical laboratory method to assess how asphalt mixtures will resist cracking over extended periods.
These research efforts reflect VTRC’s ongoing commitment to advancing innovative solutions that improve the performance, safety, and cost-effectiveness of Virginia’s transportation network.
