Good kevlar belted road tires even in 23mm should hold up fine. I rode that combination for about 5 months last year on my commute. I'm 220lb and ride 17miles of pot holed urban road including 6 rail crossings a day. My only flat was due to a cheap rim strip. I replaced the bike with one with more clearance so I could run 32mm tires. The 23s were very rough and I believe were the reason my rim failed at a spoke hole after less than a year.
However running light weight road tires I get similar results to you with at least a flat every week. Those racing tires are about as tough as butter.
