I have a project for a temporary construction road based on 19 months of traffic consisting of WB-50 vehicles (semitrailer combination). How do I determine the ESALs for this temporary road to determine a pavement thickness? My recommendation to the client was a gravel road, however, they are...
I have a meeting next week to discuss the design of a haul road for a SpacePort construction here in New Mexico. The NMDOT hopes to use gravel/base course as the temporary haul road surface treatment.
I already have a copy of the FHWA/South Dakota DOT "Gravel Roads - Maintenance and Design...
Everyone, I'm looking for a book that teaches the who, what, when and how of asphalt distress. For example, what causes bleeding? What causes alligator cracking? The cracking in this particular pavement section is considered bottom-up cracking because...sort of thing. Anyone have any ideas...

Any comments would be appreciative. I have very little experience with clays, but in the past we have always performed drained tests on sands. Also, shouldn't you always run...
Have a site in NM for a large retail center.
Historical research indicates that the site was once a quarry for concrete and we understand spoils were backfilled uncontrolled with little to no compactive effort.
Preliminary borings encountered about 25 to 33 +/- feet of loose to medium dense...

Was wondering if someone had any insight on determining the uplift capacity on a rock anchor?
Doing some tower work, with shallow refusal (<6 feet), structural engineer wants pier and mat foundation recs. Well, to prevent uplift in the mat, rock anchors have been recommended. The only thing...

Long story short, City of Albuquerque, NM, US, is looking to add 2 lanes of bikepath between 2 opposing lanes of a 2 span bridge. Area is tight (less than about 20 feet) and utilities are very near. Pipe piles due to vibrations are out, imo.
The structural has asked for micropile...
Hello everyone.
I am looking for advice on how to determine uplift resistance for drilled pier design? The pier is for a sign approaching 75 feet high.
Soils consist of medium dense to dense (N of 15 to 33 bpf) silty clayey sand underlain by stiff to very stiff lean clay (LL 49, PI32). The...
