While viewing the HTML IE 8 sets the default document mode as IE8 Standards as it should but it enters quirks mode on an asp page.
Even if I use <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
it doesn't really help.
What should I do?

First thing I would do would be place identical output in a HTM file and visit that instead. If you get different results then there really is something wierd going on because I doubt IE8 has any way to treat "asp" any differently.
BTW, How do you know its actually going into quirksmode?
What happens if you use stronger DTD like this:-
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
Does it still remain in quirksmode?
You're not confusing IE7 compatibility with Quirksmode are you?
IE7 had a number of bugs in how it render even Standards mode HTML, perhaps what are seeing is IE7 compatibility instead.
Use fiddler to examine the headers being sent with the content. Is there a header like this:-
X-UA-Compatible: IE=EmulateIE7
in the response?
Is the Compatibility button present next to address in the brower UI?

The only thing that actually works is <meta http-equiv="X-UA-Compatible" content="IE=8"/>, other browsers will ignore it but IE will be forced to be in IE-8 mode unless you've done something really stupid like putting something before the HTML.

I write standards based classic ASP all the time. The things to check would be your HTTP headers. Make sure something isn't being inserted into your HTTP header to cause it to use quirks mode. Might check your IIS box to make sure there isn't something being sent in the "Custom HTTP Headers" section in IIS. Also, check that your doctype is indeed correct. Lastly, make sure that you do not have any of IE's special meta tags that can change the rendering mode. Just because classic ASP is old doesn't mean that the browser would display it any different than any other HTML page. Honestly the browser doesn't really even care what the extension is. If it is served as html mime type then it will render as such.
