Speaker

Mohab A. Hussein, Ph.D., PE, PMP, DBIA

DIVISION OF BRIDGE ENGINEERING & INFRASTRUCTURE MANAGEMENT

NEW JERSEY DEPARTMENT OF TRANSPORTATION

Dr. Mohab Hussein, P.E., DBIA™, PMP®, is a seasoned engineer with extensive experience in the planning, design, and oversight of major infrastructure programs. As the State Geotechnical Engineer at the New Jersey Department of Transportation (NJDOT), he has overseen more than 275 transportation projects totaling over $21 billion, covering bridges, highways, tunnels, rail facilities, dams, and other key transportation assets.

Dr. Hussein also served as the New Jersey Governor’s Office representative overseeing the Gateway Program and Hudson Tunnel Project, working with Amtrak, the Port Authority of NY & NJ, the State of New York, and the Gateway Development Corporation to establish and approve technical standards for one of the nation’s most critical infrastructure initiatives. In addition, Dr. Hussein has worked directly with FEMA, providing technical expertise during emergency response operations and supporting federal–state coordination on infrastructure safety, hazard mitigation, and post-disaster assessments.

About the Project

The NJDOT Route 80 Emergency Repairs Project was implemented in Morris County to stabilize a section of I-80 impacted by sinkhole collapses linked to abandoned workings of the historic Mt. Pleasant Mine, opened in 1786. The mine, once extending 2,300 ft in length and nearly 700 ft deep, left undocumented voids and weak zones beneath the interstate. Distress first appeared in December 2024 with a 40 ft × 40 ft sinkhole, followed by additional depressions and additional failures in early 2025.
NJDOT’s emergency response integrated detailed geotechnical investigations with advanced stabilization measures. Surface geophysical methods (ground-penetrating radar, multi-channel analysis of surface waves, microgravity) and borehole surveys (sonar, acoustic and optical televiewers, video inspection) were used to characterize subsurface conditions. More than 3,000 CY of low-mobility compaction grouting was injected through a grid of boreholes to densify fractured rock and fill voids. Structural remediation included a 1,677 CY reinforced concrete slab supported by 150+ micropiles, designed to transfer highway loads onto competent strata. The project demonstrates the geotechnical challenges of reconstructing critical infrastructure over abandoned mine lands and highlights the effective use of compaction grouting, micropile-supported slabs, and accelerated construction sequencing to restore stability, durability, and resilience along one of New Jersey’s most heavily traveled corridors.
The Four Learning Objectives: 

1) Subsurface Risk Identification & Early Warning Indicators

2) Emergency Response Engineering & Temporary Stabilization Techniques

3) Permanent Stabilization, and Load Transfer Techniques

4) Designing Long-Term Solutions for Mine-Affected Corridors
