I am building a house with a drive out basement garage. I need to establish a sold base for the long term use of the driveway and for short term use by concrete trucks. Most likely the concrete trucks will be front chute 6 wheel drive models. Originally I had planned to install a 6" base of locally sourced "city pit" over the existing rocky base. I have a 640' driveway with city pit that has not washed or been disturbed in any way since 2008. It has had 22 yard dump trucks, bull dozers, excavators from 18K to 80K pounds, a large vibrating compactor and many other trucks drive over and across it without damage. The city pit material is a white limy material with chucks of rock. After the house is completed the driveway will likely be covered with chip and seal or if necessary concrete.
This is the city pit driveway on a dry day
This is the area for the new driveway
This is the same area after some additional rock removal. The driveway will follow the excavator tracks in this one.
Another one looking a little further to the South (uphill).
The challenge is that water appears to be running out of the rocks in the driveway area. I plan to have an open ditch on the uphill side of the driveway all the way to the bottom to trap water running toward the driveway. I am considering cutting trenches diagonally across the driveway every four feet or so then filling the ditches with gravel and covering with geotextile fabric before applying city pit.
What do you think of this plan? What suggestions can you make?
I have two loads of gravel and 110 yards of city pit coming Monday morning so I need to form a plan and have all supplies ready be then.
