Chart Or Publication; Human Factors
During the DINGO 5 arrival into TUS; after waypoint MAVVA; I continued on the charted 075 degree heading passing through the Runway 11L localizer course; not complying with the textual instruction to intercept the I-TUS localizer course. ATC gave me vectors back around to re-intercept the localizer course; and a normal landing was made.The cause of the event was a failure to cross-check the textual instructions with what is displayed on the chart. Contributing factors were as follows: 1) A 'Descend Via' clearance was not issued. ATC instructed to 'Descend and maintain 8;000 feet; and EXPECT a visual approach.' I misinterpreted that to mean he would provide vectors to the final approach course; or clear me for a visual approach passing MAVVA.  2) I found the verbiage on the chart confusing where it states 'Runway 11L EXPECT approach clearance'. I interpreted that to mean once established on the 075 heading from MAVVA; not upon intercepting the localizer; as normally you would not intercept a localizer without ATC clearance or prior to accepting a visual approach.To avoid a recurrence of this event; a thorough briefing covering all noted and textual information should be conducted and cross checked prior to every landing. While my briefing did cover all of the information on the plan-view of the arrival; I missed a crucial piece of information solely located in the textual description that was not well depicted nor defined on the plan-view. It would have been helpful if ATC had offered us a visual approach earlier; directed us to intercept the localized after MAVVA and THEN expect approach clearance; or have the instruction to Intercept I-TUS localizer clearly printed on the plan view. It is worthy to note; the ATC controller stated 'Yeah; you're not the first airliner to do this' both over the frequency and on the telephone while speaking with him after landing. This leads me to believe that this could be a common mistake that could be corrected easily with a revised; emphasized; note on the arrival chart.
Air carrier Captain reported a track heading deviation while on the DINGO 5 approach to TUS.  The reporter cited 'Descend Via' vs. 'Descend and maintain' phraseology and confusing chart verbiage contributed to event.
