That would be caliche, same as in New Mexico or any desert southwest area.
Just like concrete.  In fact there are some abandoned asphalt roads between 
Las Cruces, NM and Deming, NM where the asphalt was laid down on a caliche 
subgrade.  No maintenance for decades, yet there are few cracks except for 
the arroyo washouts...  Water doesn't even soften that stuff, unlike clay!
