Asphalt is just sand/gravel and tar.
Ok maybe not tar, but one of the layers of crud at the bottom of the barrel when it comes out of the cracking plant.
I worked with Asphalt for 30 years shoveling, raking it and working with paving it on High Ways.
A lighter oil/solvent just dissolves the Asphalt out of the material, especially when it is fresh. Soaks in quicker.
At NAPA I by this product, or one similar.

It`s a fine granular to a dust and really soaks up a spill. Hazmat crews, first responders use it.
Throw it on, sweep it back and forth, and depending how large the spill, sweep it off to the side and throw on some fresh. Really pulls the liquid up.
Forget Kitty using litter....
I do have three of the Kitty Litter buckets, one in ea shop and one in the garage incase I spill anything. Picked up empty ones at the recycle at the Dump.
On the concrete in front of the garage, I pour on a small amount of Wax and grease remover.
Use an old paint brush to scrub it around a bit and sweep up.
I use this brand but are others.
(Don`t you just love commiefornia? So concerned for our safety)
NOTE: This item is not for sale in the state of California
I order it from O`really`s on line and pick up in the store.
Then the Oil Soak pulls it right out of the concrete. Black old Diesel Oil? There will be some slight stain.
DA Pimple faced kid behind the counter said they don`t have it, not on the computer. Tried to sell me their brand on the shelf for $35.
Look up on my computer at home, $26 for kleen-Strip, and pick it up in the same store the next day.
When Iam changing the Engine oil, I do it on the gravel next to the shop. Helps hold down the dust if I spill any.
EDIT:...Note, do not pour the Wax & Grease remover on your Asphalt....
