No, but what's wrong with http://logback.qos.ch/access.html ?
That it only mentions Tomcat7?

In order to get Tomcat to use logback for access logs I'm assuming I'd
needed to copy the logback and sl4j-api JARs to someplace Tomcat can
find them, then set Valve/@className in server.xml accordingly, plus
provide a logback-access.xml somewhere?

FWIW, so far I've only used the built-in logging (JULI) using the
org.apache.catalina.valves.AccessLogValve valve, the
org.apache.juli.FileHandler for access logs, and the
default java.util.logging.ConsoleHandler for catalina.out.

I seem to need the org.apache.juli.FileHandler enabled in Tomcat's
logging.properties in order to be able to log access logs from a Valve
defined in server.xml, but that also creates an (unwanted) file in
org.apache.juli.FileHandler.directory (by default called
juli.log). The only way I've found to get rid of that (i.e., to only
have catalina.out and access.log, the latter via server.xml) so far
was to trick Tomcat into writing that to /dev/null:
org.apache.juli.FileHandler.directory = /dev
org.apache.juli.FileHandler.prefix = null
org.apache.juli.FileHandler.suffix =
