First, I need to identify the terms that need to be spun. The main terms here are "simplify," "design process," "engineers," "AASHTO flexible pavement design Excel spreadsheet," "tool," "input design parameters," "obtain the required pavement thickness," "design outputs," etc. Wait, but the user said to keep brand names. AASHTO is a brand name, so that should stay as is. The Excel part might be tricky since Excel is a brand. Wait, the original text says "AASHTO flexible pavement design Excel spreadsheet." Maybe "Excel" is the brand here, so that should stay. But the user says to keep brand names, so "AASHTO" and "Excel" should remain. So the rest of the terms can be spinned.

AASHTO is a brand name, so that should stay as is
